GEORGE Osborne has been accused of undermining his manifesto promises as he announces his drastic post-Brexit budget.

The Chancellor plans to put 2p on the basic rate of income tax, raise fuel duty and slash spending on health, education, defence and pensions if an 'Out' vote wins the EU referendum.

He will announce his radical emergency budget today as he outlines tax rises and cuts to frontline services of £30 billion.

The Remain campaign’s ultimatum to voters will reportedly include the possibility of increasing the higher rate of income tax by 3p, hike-up inheritance tax by 5p and put another five per cent on alcohol and fuel duties.

He said: “A future Europe will have to look at things like the free movement of labour rules.

“With freedom of movement, it’s one issue that’s coming up on the doorstep.

"A future government — whether it’s Labour or Conservative — has to hear what voters are telling them and if you look across the continent of Europe voters are telling the political elites the same thing.”
